From the Sector

SGL Carbon SE is currently evaluating various strategic options for the Business Unit Carbon Fibers (CF). These include a possible partial or complete divestment of the Business Unit. In a first step, potential interested parties shall be approached with the general data of the Business Unit to determine their interest in an acquisition. If there is sufficient interest, a structured transaction process will be carried out in a second step. Overall, a share of sales amounting to around € 179.6 million after nine months in 2023 (9M 2022: € 269.0 million) is therefore under review. The CF sales share corresponded to 21.9% of SGL Carbon's consolidated sales after nine months in 2023 (9M 2022: 31.5%). Adjusted EBITDA of the Business Unit excluding the result from joint ventures amounted to minus € 10,9 million after nine months in 2023 (9M 2022: € 27,9 million). Despite the operating loss of CF after nine months in 2023, SGL Carbon maintains its guidance for fiscal year 2023. This shows the positive development of the three other business units and the resilience of SGL Carbon's business model.

Carbon Fibers manufactures textile, acrylic and carbon fibers as well as composite materials at seven locations in Europe and North America. Following the temporary drop in demand for carbon fibers from the important wind industry market, the Business Unit's sales and earnings fell significantly in the course of fiscal year 2023. Due to the importance of the wind industry for the European Green Deal, SGL Carbon and many experts assumed that the wind industry recovers quickly. Unfortunately, this is currently not the case. Even if demand picks up, the company assumes that Carbon Fibers will need additional resources to remain competitive in the international market environment and to exploit market opportunities in the best possible way. Against this background, SGL Carbon is reviewing all possibilities to support a positive further development of the Carbon Fibers Business Unit.

In cooperation with the Swiss company Haelixa, Oerlikon Manmade Fibers Solutions will, in future, be able to make the entire value chain of a textile end product transparent and hence sustainable. The two development partners are offering a solution for the comprehensive traceability of products, as required by the European Green Deal.

An essential part of the solution is the DNA marker technology developed by Haelixa that enables complete traceability of materials. These markers survive all production process steps, validating that the end product is identifiable. "This innovative technology employs distinct DNA tailored for each project, establishing a unique identity for the material," explains Holly Berger, Marketing Director at Haelixa. "Once the DNA is integrated into the material, it becomes irremovable, impervious to falsification or alteration." Handling is straightforward: the DNA marker is fed into the spinning process with the preparation oil, for example. The preparation system is modified accordingly. Further feeding options are currently being developed.

Smart factory: total transparency with atmos.io
The concept is complemented by atmos.io, Oerlikon's digital platform, which records and evaluates extensive production and process data during the yarn manufacturing process. Atmos.io gives the yarn its digital identity during its time on Oerlikon systems, from the melt to the packaged package. This technology has been used successfully for some time to monitor the production process. With atmos.io, deviations in process parameters and yarn data can be identified and rectified within a very short time, which in turn keeps the yarn quality stable and reduces waste rates.

Combining both technologies enables clear traceability of the yarn produced, even in the downstream process steps. Hence, the yarn's components, qualities, manufacturing conditions, and origin are traced beyond doubt in the finished garment. "The unique DNA carries the 'roots' of the yarn digitally recorded in atmos.io into the everyday life of the end consumer," says Jochen Adler, CTO at Oerlikon Manmade Fibers. The textile end products meet the requirements of the digital product passport required by the EU, which contains the information needed to assess their life cycle assessment and circularity. Initial long-term tests have shown 100% traceability of the yarns in the POY and FDY spinning process. If the yarn manufacturer relies on the atmos.io platform, production systems can be adapted relatively easily to use the DNA markers.
